SOHO discovers its 1,500th comet

The ESA/NASA SOHO spacecraft has just discovered its 1500th comet, making it more successful than all other comet discoverers throughout history put together. Not bad for a spacecraft that was designed as a solar physics mission.

SOHO's record-breaking discovery was made late on 25 June. When it comes to comet catching, the SOlar and Heliospheric Observatory has one big advantage over everybody else: its location. Situated between the Sun and Earth, it has a privileged view of a region of space that can rarely be seen from Earth. From the surface, we can see regions close to the Sun clearly only during an eclipse.



In 1807, a comet appeared in the Natchez night sky

On Tuesday, March 1, 1808, Judge Thomas Rodney wrote a letter to his son -- U.S. Attorney General Ceasar Rodney -- with news of the sighting of a comet in the Natchez sky.


Did Life Begin In Space? New Evidence From Comets; Author responds to criticisms

Recent probes inside comets show it is overwhelmingly likely that life began in space, according to a new paper by Cardiff University scientists.


NASA Finds New Type of Comet Dust Mineral

HOUSTON -- NASA researchers and scientists from the United States, Germany and Japan have found a new mineral in material that likely came from a comet.

The mineral, a manganese silicide named Brownleeite, was discovered within an interplanetary dust particle, or IDP, that appears to have originated from comet 26P/Grigg-Skjellerup. The comet originally was discovered in 1902 and reappears every 5 years. The team that made the discovery is headed by Keiko Nakamura-Messenger, a space scientist at NASA's Johnson Space Center in Houston.

"When I saw this mineral for the first time, I immediately knew this was something no one had seen before," said Nakamura-Messenger. "But it took several more months to obtain conclusive data because these mineral grains were only 1/10,000 of an inch in size."


Comet Boattini Sails Towards the Sun

Serious comet chasers have been watching Comet C/2007 W1 (Boattini) for some time. For awhile, it exceeded its predicted brightness but is back to cruising at normal. During the time this photograph was taken, Boattini was a southern hemisphere object... But not for long. Now its about to round the Sun and head north!

The Destruction of Zhou Man and Hong Bao's fleets in the Southern Ocean by a Tsunami triggered by a comet

In the book '1421', I contended that the Emperor Zhu Di had sent fleets to the Southern Ocean to determine the precise position of the star Canopus. The Chinese needed this information to establish accurate latitudes and longitudes in the southern hemisphere. (United Kingdom paperback edition, pages 161-3, and diagram 1).

Since the book was published we have received more than 100,000 e-mails and letters and millions of people have visited our website 'www.1421.tv'. These visitors from over 130 countries around the world have brought new evidence. To date the most important has been my underestimation of the scale of the undertaking. Instead of 100 ships, over 1000 set sail (800 arrived at Calicut alone). There were many great voyages - Fleets were continuously at sea from 1403 to 1432 and the scale of the losses was even more horrific - more than 900 ships never returned. This is exemplified in the Southern Oceans. The discovery of Zheng He's records shows that four separate fleets charted the Antarctic not the two I have claimed. Some got further south - deep into the Weddell Sea.

This memo describes a catastrophe which overtook the fleets which had sailed south of New Zealand down to Campbell Island and Auckland Island (pp.206-209 of United Kingdom Paperback edition). A huge comet struck the ocean less than a hundred miles from the fleets, incinerating many ships and hurling the blazing wrecks onto New Zealand South Island and the East coasts of Australia, and across the Pacific and Indian Oceans.

Proof found of man-made climate change, Scientists fear public won't care after a comet falls on their head

Scientists have been able to say with virtual certainty for the first time that the climate change observed over the past four decades is man made and not the result of natural phenomena.


Comets, dragons & prophets of doom

Ancient myths suggest that a giant comet may have visited the Earth a few thousand years ago, raining fireballs and meteors

Scientists are starting to recognise that the evolution of life on Earth has been affected, if not largely shaped, by its celestial environment. We now recognise that throughout its history the Earth has been bombarded by comets, small asteroids, meteorites (small rocky or iron bodies) and smaller particle and dust (meteor) showers. Over the years, astronomers have detected a substantial population of such small bodies out there in the Solar System, confirming that the threat of their impact with the Earth is a significant one. Current estimates, for example, suggest that between 10 and 30 impacts similar to the one that occurred in Tunguska in Siberia in 1908 have happened over recorded history, with perhaps one or more exploding with a force equivalent to that produced by 500 to 1000 megatonnes of TNT.

High School freshman unearths asteroid, cometary evidence for mammoth extinction

After working countless hours digging soil samples and analyzing them with sophisticated microscopes, Great Falls High School freshman Katelyn Gibbs has come up with evidence that a comet or meteorite crashed to Earth in Montana 13,000 years ago and had major impact on animals living here at the time.

"Bing! She nailed it!" said David Baker of Monarch, a veteran earth science research scientist who mentored Gibbs on the project. "Katelyn found definitive proof - nanodiamonds and iron micrometeorites - for the extraterrestrial impact event that killed the mammoths in Montana.


Comets might have caused ancient American extinctions 13,000 years ago

Scientists have come up with a controversial theory which suggests that huge comet impacts wiped out North America's large mammals 13,000 years ago.

According to a report in National Geographic News, the hypothesis, first presented in May 2007, proposes that an onslaught of extraterrestrial bodies caused the mass extinction known as the "Younger Dryas event" and triggered a period of climatic cooling.
